Abstract
Disclosed embodiments relate to a method implementable on a computing device for modifying color characteristics of an image. The method includes identifying one or more regions in the image based on a luminance value associated with one or more pixels in the image. Each region comprises a first set of pixels having a predefined range of luminance values. The first set of pixels is categorized in a first set of predefined color categories corresponding to the each region based, at least in part, on a chroma value associated with each pixel in the first set of pixels. Each predefined color category in the first set of predefined color categories comprises a second set of pixels. The color characteristics of the second set of pixels are modified based on a region and a predefined color category associated with the second set of pixels.
